Limit Switches
The mechanical limit switches are normally closed (when not activated) and
should be connected to a compatible controller that recognizes these settings.
Failure to properly set up the limit switches in the controller will result in physical
damage to the MPA-20 Linear Actuator.
The mechanical limit switches are factory calibrated for a minimum travel of
12mm (when the switches are initially activated). Customer adjustment of the
limit switches is not recommended. For custom travel lengths, please contact
MICRONIX USA.
